A second sample of Frank Schleck's urine taken on Saturday July 14 during the 2012 Tour de France has also tested positive for a banned substance, both the Luxembourg rider  and UCI confirmed on Friday.

The Union Cycliste Internationale (UCI) announced on Tuesday that the World Anti-Doping Agency accredited Châtenay-Malabry laboratory had detected banned diruetic xipamide in Schleck's A sample. Schleck then took up his right to have the B sample tested, and this has also returned a positive for xipamide, according to the UCI.
